Stereo Lithography Apparatus - SLA

Stereo Lithography Apparatus - SLA

We offer stereolithography apparatus that is processed using photosensitive resins cured by a laser that traces the parts cross sectional geometry layer by layer. SLA produces accurate models with a variety of material choices. The SLA method uses liquid photopolymer resins that are solidified by a laser to generate parts. The build platform, which translates up and down, is suspended in the vat of resin. The build platform is placed slightly under the surface of the resin. A laser beam hardens the resin when it makes surface contact. Depending on the material, a post cure operation is sometimes needed to attain the desired material properties. After any final curing, the support structures that were built to prevent any sagging are removed.

Selective Laser Sintering - SLS

Selective Laser Sintering - SLS

We offer Selective laser sintering that is an additive for rapid manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal, or ceramic powders into a mass representing a desired 3-dimensional object. The laser selectively fuses powdered material by scanning cross-sections generated from a 3-D digital description of the part (for example from a CAD file or scan data) on the surface of a powder bed. After each cross-section is scanned, the powder bed is lowered by one layer thickness, a new layer of material is applied on top, and the process is repeated until the part is completed.

Compared to other rapid manufacturing methods, SLS can produce parts from a relatively wide range of commercially available powder materials, including polymers (nylon, also glass-filled or with other fillers, and polystyrene), metals (steel, titanium, alloy mixtures, and composites) and green sand. The physical process can be full melting, partial melting, or liquid-phase sintering. And, depending on the material, up to 100% density can be achieved with material properties comparable to those from conventional manufacturing methods. In many cases large numbers of parts can be packed within the powder bed, allowing very high productivity.

SLS is performed by machines called SLS systems; the most widely known model of which is the Sinterstation SLS system. SLS technology is in wide use around the world due to its ability to easily make very complex geometries directly from digital CAD data. While it began as a way to build prototype parts early in the design cycle, it is increasingly being used in limited run manufacturing to produce end-use parts. One less expected and rapidly growing application of SLS is its use in art.

Fused Deposition Modeling - FDM

Fused Deposition Modeling - FDM

Fused deposition modeling, which is often referred to by its initials FDM, is a type of rapid prototyping or rapid manufacturing (RP) technology commonly used within engineering design. The technology was developed by S. Scott Crump in the late 1980s and was commercialized in 1990. The FDM technology is marketed commercially by Stratasys Inc.

Like most other RP processes (such as 3D Printing and stereolithography) FDM works on an "additive" principle by laying down material in layers. A plastic filament or metal wire is unwound from a coil and supplies material to an extrusion nozzle which can turn on and off the flow. The nozzle is heated to melt the material and can be moved in both horizontal and vertical directions by a numerically controlled mechanism, directly controlled by a Computer Aided Design software package. In a similar manner to stereolithography, the model is built up from layers as the material hardens immediately after extrusion from the nozzle.

FDM technology can also be used with polycarbonates, polycaprolactone, polyphenylsulfones and waxes. A "water-soluble" material can be used for making temporary supports while manufacturing is in progress. Marketed under the name WaterWorks by Stratasys this soluble support material is actually dissolved in a heated sodium hydroxide solution with the assistance of ultrasonic agitation.

Polyjet Process

Polyjet Process

We offer our clients the services of polyjet process where in we use latest technological systems to produce parts directly from CAD files in any one of the several materials available. Also termed as multi jet modeling, this is a process where photopolymers are jetted on to a build platform, and then parts are built by layer by layer giving a very accurate rigid model. We utilize this technique as a new direction in 3- D printing enabling simultaneous jetting of different type of model materials capable of producing prototypes of finest up to 16 microns (Z-AXIS) with acrylic output.

Rapid Tooling Service

Rapid Tooling Service

This Rapid Prototyping services has also been referred to as solid free-from manufacturing, computer automated manufacturing, and layered manufacturing. RP is used as a vehicle for visualization. In addition, RP models can be used for testing, such as when an airfoil shape is put into a wind tunnel. RP models can be used to create male models for tooling, such as silicone rubber molds and investment casts. In some cases, the RP part can be the final part, but typically the RP material is not strong or accurate enough. When the RP material is suitable, highly convoluted shapes (including parts nested within parts) can be produced because of the nature of RP.

There is a multitude of experimental RP methodologies either in development or used by small groups of individuals. This section will focus on RP techniques that are currently commercially available, including Stereolithography (SLA), Selective Laser Sintering (SLS®), Laminated Object Manufacturing (LOM™), Fused Deposition Modeling (FDM), Solid Ground Curing (SGC), and Ink Jet printing techniques.

Injection Molding Services

Injection Molding Services

The injection molding services offered by us is a manufacturing technique for making parts from both thermoplastic and thermosetting plastic materials in production. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of cars. Injection molding is the most common method of production, with some commonly made items including bottle caps and outdoor furniture. This can also be used to manufacture parts from aluminium or brass (die casting). The melting points of these metals are much higher than those of plastics; this makes for substantially shorter mold lifetimes despite the use of specialized steels. Nonetheless, the costs compare quite favorably to sand casting, particularly for smaller parts.
